History VideoGame / GarrysMod

* {{Retraux}}: Quite a few addons involve recreating weapons, maps, or [=NPCs=] from older games, in full pixelated or polygonal glory. There's even a mod that takes the appropriate ''VideoGame/{{Doom}}'' IWAD, provided by the player, recreating the weapons and monsters faithfully by using the original's UsefulNotes/GameEngine.

** Large, gangly ragdolls can be a nightmare, and can potentially kill you if you're too close while the physics causes them to flail about because you moved their arm a pixel in the wrong direction. The author of ''Webcomic/{{Concerned}}'' once got killed while posing a Strider, as the Physics Gun jerked the Strider's leg too fast at him. Can be offset by placing heavy objects near them, to help control their jerkiness. Possibly-relatedly, he only had a posed Strider show up in one other comic, nearly two years later.

** There exist maps that are "void" edits of other maps (for example, gm_construct and gm_construct_void). These are impossible to navigate through without the flashlight. The description for Gm_Bigcity_Void is pretty simple: "The city was shrouded in void, no people, no sounds, [[UnspecifiedApocalypse nothing that could tell what had happened here]]".

* OurZombiesAreDifferent: In the base game, there are only [[VideoGame/HalfLife Headcrab zombies]], but you can install mods that add anything from the VideoGame/{{Minecraft}} zombies to [[Website/SCPFoundation SCP-008 carriers]]. There's even [[VideoGame/ZombieSurvival an entire gamemode]] dedicated to them.
* LeParkour: Possible using parkour add-ons ([=SaVav=] Parkour Mod, Wheatley's Parkour, the Parkour Swep[[note]]a scripted weapon which allows you to jump large distances and negates falling damage[[/note]], Perfected Climb Swep[[note]]a scripted weapon that allows you to climb and grab onto ledges[[/note]], Smod Leg[[note]]The glorified kick from SMOD[[/note]], Gordon's Fists, or Beatrun[[note]]a custom game mode which adds ''VideoGame/MirrorsEdge''-esque movement and mechanics and allows you to run user-created courses[[/note]]) and a big, urban themed map (such as gm_bigcity or gm_goldencity).

* RuleOfFun: Oh so much. Highlights include building random things out of props, destroying them, making NPC's fighting each other, destroying them, blowing up stuff with nukes, downloading addons, destroying them, etc.

* ScienceFiction: The Spacebuild gamemode, usually used in combination with the futuristic props of the Spacebuild Enhancement Project. Not that's there anything stopping you from just sticking a oxygen tank on a UsefulNotes/WorldWarII fighter and flying off to Neptune, though.

* CoolGuns: There are numerous SWEP guns on the Workshop, ranging from standard guns to admin guns that can one-shot any player or NPC. You can also build your own with customizable weapon frameworks such as [=ArcCW=] and TFA Base.

As a sandbox with no set objectives, the game gives you the tools to take full advantage of ''Half-Life 2's'' physics engine and assets, as well as those of various Source engine games like ''VideoGame/CounterStrike'', ''VideoGame/TeamFortress2'', and ''VideoGame/Left4Dead'', etc. You can spawn and bind together props to build all sorts of structures and machinations such as buildings, HumongousMecha, cannons, catapaults, etc. You can set armies of [=NPCs=] against each other. And with a library of ragdolls at your disposal, you can even freely manipulate and pose them them to create whatever demented setpiece or puppet show you want.

The game uses the UsefulNotes/{{Lua}} scripting language for its weapons and events, meaning it's possible to code your own weapons into the game and publish them to the Steam Workshop, along with user-created maps, props, vehicles, entities, [=NPCs=], effects, and models, resulting in a ''highly'' customizable game. Currently, it's available on Valve's UsefulNotes/{{Steam}} client [[http://store.steampowered.com/app/4000 for download.]]

* FirstPersonSnapshooter: The Camera allows you to take pictures from in-game and have them saved to file (and {{UsefulNotes/Steam}} screenshots as if you pressed F12). Hence, there have been many WebComics created via Garry's Mod.

* PlayerCreationSharing: [=GMod=] 12 had the Toybox, which allowed the player to install mods and load them in-game. In [=GMod=] 13, this was replaced by UsefulNotes/{{Steam}} Workshop support, though you can install dupes and saves in-game.

* ScienceFiction: The Spacebuild gamemode, usually used in combination with the futuristic props of the Spacebuild Enhancement Project. Not that's there anything stopping you from just sticking a oxygen tank on a UsefulNotes/WorldWar2 fighter and flying off to Neptune, though.

** Similar to gmDoom mentioned above, there is also [[https://steamcommunity.com/sharedfiles/filedetails/?id=2814638140 G64]], which uses a ROM from ''VideoGame/SuperMario64'' to recreate how Mario plays in the game, and [[https://steamcommunity.com/sharedfiles/filedetails/?id=2842201165 GMBlox]], which attempts to recreate how ''VideoGame/{{Roblox}}'' played during the late 2000s.

** Taking a close look at the Tool Gun reveals that it has a [[Film/BackToTheFuture flux capacitor]] on it.

* CopyProtection: If the game detects it's pirated, it will pretend to crash and display the nonexistent error "Unable to shade polygon normals" with an "error message" that is actually the user's Steam ID, in order to trick pirates into posting about it on the forums and getting themselves banned.

** The Hobo from [=DarkRP=]. No salary, [[BodyHorror looks like a corpse]], only has the ability to throw crap at people (literally), and often the AcceptableTargets [[FinalSolution for purging]] by particularly sadistic mayors.[[invoked]]

* BlackoutBasement: The default map ''gm_construct'' has a dark room accessible via either a brick warehouse building, or a staircase embedded into one of the map's walls. It's meant for testing out lights, meaning there are absolutely zero lights, requiring the player to either use their flashlight or place down lights/lamps via the Tool Gun.

** The default gamemode icon is a blue ''Toys/{{LEGO}}'' brick.

* ShoutOut: In the Context Menu, there is an option called [[VideoGame/{{Minecraft}} Minecraftify]]. It [[StylisticSuck pixelates]] all of the textures, just as the name would lead you to think.

** A similar mod is the [[https://steamcommunity.com/sharedfiles/filedetails/?id=2837856621 Lightsaber Combat System]]. It's similar, but allows for much more complex movement, blocking, and lightsaber duels.

* LaserBlade: The [[https://steamcommunity.com/sharedfiles/filedetails/?id=111412589 Star Wars Lightsabers]] mod brings [[Franchise/StarWars the originals]] into the game. It is extremely customizable, and unlike most melee weapons, can kill without the need to swing (simply touching the blade is usually fatal), just like in the films.

* StreamingStars: In the various ''Franchise/StarWars'' themed maps, this comes into effect when entering and exiting hyperspace.

''Garry's Mod'' (or ''[=GMod=]'') is a sandbox physics game developed by Facepunch Studios and published by Creator/ValveCorporation, originally [[ExactlyWhatItSaysOnTheTin a mod created by Garry Newman]] of Valve's own ''VideoGame/HalfLife2''. Initially just the latter game with the rope, manhack and rollermine guns being the only additions, it has evolved considerably since then to the point of becoming its own standalone game.

* LudicrousGibs: Generally averted in the main game; when killed, the player's corpse flops onto the ground (or disintergates when hit with an EnergyBall). There ''are'' a lot of mods that can make players into meat explosives, though.

* SistineSteal: One of the few original models is gm_painting, which is Creation Of Adam with Garry edited in.

* InfiniteFlashlight: Compared to the TenSecondFlashlight of the Half Life series, G-Mod's flashlight will stay on infinitely. This is rather useful when it comes to navigating maps ostensibly set at night or horror maps.

* LudicrousGibs: The [[http://www.garrysmod.org/downloads/?a=view&id=52104 Dismemberment Mod]]. The [[https://www.youtube.com/watch?v=MeHfNcleaOo Gore Mod]] probably takes home the gold, though.

* HarmlessVillain: Aside from giving a good scare now and then, "Semper" from gm_construct_13_beta does absolutely no harm to the player and will automatically disappear after a few seconds.
